OP, your first post on this thread was on New Year's Eve and you were 20 weeks and 4 days pregnant.
It's a very serious matter that your GP is still failing to refer you to a hospital and you need to access midwifery care as soon as possible. If this is really what's happening then she has failed in her duty of care. Not to mention being in blatant disregard of many different guidelines and procedures.
You need to be reporting this GP at once, not relying on her as your only source of support.
At the booking in appointment conducted by the midwife that is offered as standard to every pregnant woman throughout the UK, they take down vital medical and social history, do tests to check for risk factors and special measures they might need to take to protect yours and the babies health, and they also go through the process and choices that you'll need to make throughout the entire pregnancy, from ultrasound scans, nuchal tests to birth plans, gestational diabetes, babies growth and development etc etc etc.
It is possible to refuse all healthcare but very unusual, and it wouldn't be something health care professions would be happy for you to do, especially as it seems like you don't understand the system or what's on offer as routine to look after you and your unborn child. This isn't something GPs or the wider NHS takes lightly and it's not something a GP would gamble their job over.
I'm sorry to sound harsh OP but you appear to be sleep-walking into some kind of complete disaster, which isn't usual and I find it so confusing about how you are managing to avoid every source of help available that anyone else in your position would be able to access without going out of their way at all, just being swept along in the usual process would get you in front of people that can help you. Or maybe there is something else going on here that you need a lot of help with and I really hope you get it.
